[0023] As mentioned briefly above, the existing heating methods of atomization cores have problems such as limited temperature regulation range, fixed heating region, and poor adaptability. Specifically, the existing atomization core adopts a metal coil, a mesh core structure, a ceramic substrate, or the like as a heating element. The metal coil is widely used due to its simple structure and rapid heating performance, but it is prone to the problems such as local overheating or insufficient temperature control, which affects the full atomization of the aerosol precursor. A linear heating method of the mesh core structure can provide a larger heating area compared with a traditional metal coil, however, due to its relatively thin heat-conducting structure, it is prone to shortened service life due to uneven power distribution, and the production difficulty is high; and a surface heating method of the ceramic core can achieve relatively uniform surface heating, however, the ceramic substrate has relatively low thermal conductivity and limited power response speed. In addition, the existing atomization core cannot meet the requirements for precise control and adaptability of temperature, making it difficult to meet the personalized requirements of different users on atomization volume.
[0024] In order to solve or at least partially solve the above problems or other potential problems of the atomization core in existing solutions, embodiments of the present disclosure provide a solution of an atomization core for an atomization apparatus and the atomization apparatus. According to various embodiments of the present disclosure, the atomization core includes a substrate, a pair of heating films, and a conductor. Further, the substrate includes an intake surface and an atomization surface arranged opposite to each other, a plurality of through holes, and a pair of electrodes. Further, the intake surface is arranged adjacent to a receiving cavity for receiving an aerosol precursor. The plurality of through holes are configured to penetrate through the intake surface and the atomization surface and allow the aerosol precursor of the atomization apparatus to flow from the intake surface to the atomization surface. The pair of electrodes are arranged on at least one of the intake surface and the atomization surface. Further, the pair of heating films are respectively arranged on the intake surface and the atomization surface, and coupled between the pair of electrodes. Further, the conductor is arranged in at least one through hole of the plurality of through holes, and is adapted to establish a conductive connection between the pair of electrodes and between the pair of heating films.
[0025] In this way, the heating films are respectively arranged on the intake surface and the atomization surface of the substrate, the sufficient flow of the aerosol precursor and the efficient electrical connection of the conductor are realized through the plurality of through holes penetrating through the substrate, and thus the heating efficiency and the atomization effect of the atomization core are significantly improved. Meanwhile, the aerosol precursor can be heated from both the intake surface and the atomization surface simultaneously through the double-sided heating film structure, avoiding local overheating or cooling caused by a traditional single-sided heating method, and further enhancing the atomization effect and the utilization rate of the aerosol precursor. Through the cooperation of the pair of electrodes and at least one conductor, and the series or parallel connection between the pair of heating films, the flexible regulation of temperature and power can be realized to meet diverse usage requirements.
[0026] The structure of the atomization apparatus will be described below. In embodiments of the present disclosure, the atomization apparatus includes a power supply, a circuit unit and an atomization core 100. Through cooperation of the power supply, the circuit unit, and the atomization core 100, the atomization apparatus aims to realize the heating and atomization of an aerosol precursor, thereby providing an efficient and stable atomization effect, and ensuring the safety and reliability of the atomization process through a temperature control and protection mechanism.
[0027] Further, the power supply of the atomization apparatus provides needed electrical energy for the atomization apparatus. The power supply may be a rechargeable battery, an external power adapter, or other suitable power supply devices, which is not specifically limited in embodiments of the present disclosure. The voltage and current provided by the power supply are used to drive the atomization core 100 to operate. The voltage and current output by the power supply can be adjusted according to the requirements of the circuit unit to meet the power requirements needed for heating the atomization core 100.
[0028] Further, the circuit unit is configured to regulate the current provided by the power supply, so as to control the temperature of the atomization core 100. In some embodiments, the circuit unit includes a temperature control circuit, a power regulation circuit, and the like, to ensure that the atomization core 100 can be stably heated during operation, and be automatically powered off under abnormal conditions to protect the device. Therefore, through the regulation of the circuit unit, the intensity and duration of the current can be precisely adjusted, thereby adjusting the temperature of the atomization core 100, and further controlling the atomization process.
[0029] Further, the atomization core 100 is used to convert electrical energy provided by the power supply into thermal energy, and heat the aerosol precursor to achieve atomization. The aerosol precursor may be a liquid oil or other substances suitable for atomization.
[0030] During the operation of the atomization apparatus, the power supply provides electrical energy to the circuit unit, and the circuit unit regulates the output current according to the operation mode set by the user. The current is conducted to the atomization core 100, causing it to start being heated and generate heat, and the aerosol precursor evaporates to form atomized gas during the heating process. The circuit unit can monitor the temperature of the atomization core 100 in real time, ensuring it is within a predetermined range to prevent excessively high or low temperature from affecting the atomization effect.
[0031] In this way, the circuit unit can achieve precise temperature regulation, ensuring that the atomization core 100 operates within a suitable operating temperature range, and improve the stability of the atomization effect. By adjusting the current magnitude, the atomization apparatus can adapt to different types of aerosol precursor to meet different user requirements.
[0032] The atomization core 100 according to embodiments of the present disclosure will be described below with reference to FIGS. 1 to 3. FIGS. 1 to 3 show schematic structural diagrams of the atomization core 100 according to some embodiments of the present disclosure. As shown in FIGS. 1 to 3, the atomization core 100 according to embodiments of the present disclosure generally includes a substrate 110, a pair of heating films 130, and a conductor 140, which is intended to achieve an efficient and uniform atomization effect while improving temperature control and safety. Specific implementations thereof are described in detail below:
[0033] Further, the substrate 110 of the atomization core 100 includes two opposite surfaces (i.e., an intake surface 101 and an atomization surface 102 described below) , a plurality of through holes 1101, and a pair of electrodes 120. Specifically, the two opposite surfaces include the intake surface 101 and the atomization surface 102, and the intake surface 101 is arranged adjacent to a receiving cavity for receiving the aerosol precursor. Further, the substrate 110 may be made of a material with high temperature resistance and excellent insulating properties, such as quartz glass, ceramic, glass fiber composite material, or polymer material, which is not specifically limited in embodiments of the present disclosure.
[0034] Further, the plurality of through holes 1101 are formed in the substrate 110, and the through holes 1101 penetrate through the intake surface 101 and the atomization surface 102 of the substrate 110, and allow the aerosol precursor (such as E-liquid or other liquid) of the atomization apparatus to flow from the intake surface 101 to the atomization surface 102. The size and distribution of the through holes 1101 may be arranged according to actual atomization requirements to ensure smoothness and uniformity of liquid flow.
[0035] Further, the pair of electrodes 120 are arranged on at least one of the intake surface 101 and the atomization surface 102 of the substrate 110, and are used to provide electrical energy to the heating films. The electrode may be made of a metal material with high conductivity, such as silver, copper, aluminum, or nickel alloy, and is fixed on the surface of the substrate 110 by a process such as deposition, sputtering, or printing, which is not specifically limited in embodiments of the present disclosure. In this way, reliable connection between the electrodes and the power supply can be ensured, and uniform distribution of current in the heating films can be achieved. In some embodiments, the pair of electrodes 120 of the atomization core 100 are respectively connected to the power source and the circuit unit. The power supply provides electrical energy to the electrodes through the circuit unit, the current flows to the pair of heating films through the electrodes, thereby heating the aerosol precursor.
[0036] The pair of heating films 130 of the atomization core 100 continue to be described. The pair of heating films 130 are respectively arranged on the intake surface 101 and the atomization surface 102 of the substrate 110, and are heated through electrical coupling between the electrodes, causing the aerosol precursor to evaporate rapidly and be converted into a gas state, so as to form an aerosol. The material of the heating film may be selected from materials with good thermal conductivity and high temperature resistance, such as a conductive ceramic, a carbon-based material, or a metal alloy film, which is not specifically limited in embodiments of the present disclosure.
[0037] The heating films on an upper side and a lower side may be made of the same material or different materials to meet different functional requirements, such as single-sided efficient heating or double-sided temperature regulation. The geometric shape, thickness, and coverage range of the heating film may be selected according to needed proportion of heating area, which is not specifically limited in embodiments of the present disclosure. Optionally, a temperature sensor may monitor the real-time temperature of the heating films and feed back the real-time temperature to the circuit unit for fine regulation.
[0038] Further, the conductor 140 is arranged in at least one through hole 1101 of the plurality of through holes 1101 of the substrate 110, and is used to establish a conductive connection between the pair of heating films 130 and between the pair of electrodes 120. The conductor 140 may adopt a material with good electrical conductivity and mechanical stability, such as a metal material or a conductive composite material, which is not specifically limited in embodiments of the present disclosure. For example, the number of the conductors 140 is at least one. In this way, the conductor 140 can flexibly adjust the electrical connection method between the heating films, for example, realizing series or parallel connection of the heating films on two sides, thereby further controlling the heating power and the temperature distribution of the atomization core 100.
[0039] When the power source provides current to the pair of heating films 130 through the pair of electrodes 120, the pair of heating films 130 are rapidly heated and transfers heat to the aerosol precursor, thereby atomizing the liquid into the aerosol. The heating film on a side can be used to directly heat the atomization area, and the heating film on the other side can be used for preheating or temperature compensation of the aerosol precursor on the back side. Meanwhile, by adjusting the number and position of the conductor 140 in the through holes 1101, the conduction ratio of the heating films on the upper side and the lower side can be controlled, thereby achieving different proportional distributions of the double-sided heating area, and further improving the atomization performance and temperature control.
[0040] In this way, the atomization core 100 not only can achieve efficient atomization and temperature regulation, but also can improve safety, so as to be suitable for applications in various electronic atomization apparatus.
[0041] In some embodiments, the atomization surface 102 is located on an opposite side of the intake surface 101, and is a surface for directly realizing the atomization function. Both the intake surface and the atomization surface may be provided with the heating film, to convert the aerosol precursor conducted from the intake surface 101 into the aerosol through preheating and heating. In addition, the atomization surface 102 is arranged on an air outlet path facing the atomization apparatus, ensuring that the generated aerosol can be output to the user's inhalation port.
[0042] Further, the intake surface 101 and the atomization surface 102 realize linkage of fluid and heat through the plurality of through holes 1101 of the substrate 110. Specifically, the intake surface 101 may guide the aerosol precursor from the receiving cavity to the plurality of through holes 1101 of the substrate 110 via the heating film. The aerosol precursor flows along the plurality of through holes 1101 to the atomization surface 102, and rapidly vaporizes into the aerosol under the heating action of the heating film of the atomization surface 102.
[0043] As shown in FIG. 1, in some embodiments, the pair of electrodes 120 are respectively arranged on the intake surface 101 and the atomization surface 102 of the substrate 110. Further, the pair of electrodes 120 may be arranged at two ends of the substrate 110, respectively. Specifically, the pair of electrodes 120 includes a first electrode 1201 and a second electrode 1202, the first electrode 1201 is arranged at an end of the substrate 110, the second electrode 1202 is arranged at an end opposite to the first electrode 1201, and the first electrode 1201 and the second electrode 1202 are respectively arranged on the intake surface and the atomization surface. Further, the first electrode 1201 is arranged on the intake surface 101, and is used to provide electrical energy to a first heating film 1301 of the pair of heating films 130 arranged on the intake surface 101. Further, the second electrode 1202 is arranged on the atomization surface 102 and is used to provide electrical energy to a second heating film 1302 of the pair of heating films 130 arranged on the atomization surface 102.
[0044] This not only enables distributed power supply of the circuit, but also ensures that the heating films on the intake surface 101 and the atomization surface 102 can operate independently or cooperatively, and the temperature and the heating power can be flexibly regulated according to requirements.
[0045] Further, the pair of heating films 130 includes a first heating film 1301 and a second heating film 1302. The first heating film 1301 is coupled to the first electrode 1201, covers a first partial region of the intake surface 101, and is used to heat the intake surface 101 to improve the transmission efficiency and the preheating effect of the liquid.
[0046] Further, the first heating film 1301 includes a plurality of first vias 1303 aligned with the through holes 1101 in the first partial region of the intake surface 101, so as to ensure that the aerosol precursor can flow from the intake surface 101 to the atomization surface 102 through the through hole 1101.
[0047] Optionally, the material of the first heating film 1301 may be selected from materials with good high temperature resistance and good conductivity, such as a metal, alloy film, or a conductive ceramic, which can provide a stable heating effect under a low power condition and reduce energy loss.
[0048] Further, the second heating film 1302 is coupled to the second electrode 1202, covers a second partial region of the atomization surface 102, and is used to heat the aerosol precursor transmitted to the atomization surface 102, thereby realizing rapid atomization.
[0049] Further, the second heating film 1302 includes a plurality of second vias 1304 aligned with the through holes 1101 in the second partial region of the atomization surface 102, so as to allow the aerosol precursor transmitted from the intake surface 101 to pass through smoothly, and meanwhile ensure the heating uniformity and the atomization efficiency of the second heating film 1302.
[0050] Optionally, the material of the second heating film 1302 may be selected to be the same as or different from that of the first heating film 1301 according to requirements. For example, if a higher atomization temperature is required, a metal-based material with a higher thermal conductivity can be selected; if the safety needs to be enhanced, a low-melting-point material with a fusing function can be selected, which is not specifically limited in embodiments of the present disclosure. When the material of the second heating film 1302 is different from that of the first heating film 1301, for example, the material of the first heating film 1301 is more resistant to dry burning than that of the second heating film 1302, that is, the second heating film 1302 is prone to film breakage when dry burning occurs, specifically, the material of the first heating film 1301 is a gold-silver alloy film or a stainless steel material film, and the material of the second heating film 1302 is a titanium-zirconium alloy film or an aluminum film. There is a special advantage that when the E-liquid is exhausted, the film can be broken in time, avoiding harmful gas released due to continuous dry burning from being inhaled by humans, thus making the use of such atomization apparatus healthier and safer.
[0051] When the atomization apparatus operates, the current is transmitted to the first heating film 1301 and the second heating film 1302 through the pair of electrodes 120, respectively. The first heating film 1301 heats the intake surface 101, preheats the aerosol precursor, to improve fluidity thereof and reduce condensation phenomenon. Through the through holes 1101, the preheated aerosol precursor is transmitted from the intake surface 101 to the atomization surface 102, and rapidly vaporizes into the aerosol under the heating action of the second heating film 1302.
[0052] In some embodiments, the conductor 140 is coupled between the first heating film 1301 and the second heating film 1302 by passing through a corresponding through hole 1101. The electrical connection between the intake surface 101 and the atomization surface 102 is achieved by the conductor 140, and the heating uniformity and the energy transmission efficiency are further improved.
[0053] Specifically, the conductor 140 passes through a corresponding through hole 1101 and is coupled to the first heating film 1301 on the intake surface 101 and the second heating film 1302 on the atomization surface 102. The conductor 140 is not only used for electrically conducting but also facilitates heat transfer, thereby improving the heating efficiency of the whole atomization core 100.
[0054] In some embodiments, on the intake surface 101, the conductor 140 is coupled to a side of the first heating film 1301 away from the first electrode 1201. On the atomization surface 102, the conductor 140 is coupled to a side of the second heating film 1302 away from the second electrode 1202.
[0055] Such arrangement method can ensure that the current passes the conductor 140 and a continuous conductive path is formed between the first heating film 1301 and the second heating film 1302, thereby realizing a series operation mode of the heating films on the two surfaces.
[0056] Through the series operation mode, the first heating film 1301 and the second heating film 1302 can jointly accomplish double-sided heating of the atomization core 100. The current firstly enters the first heating film 1301 through the first electrode 1201 to preheat the aerosol precursor on the intake surface 101. The preheated aerosol precursor is transmitted to the atomization surface 102 through the through holes 1101, and the conductor 140 transmits the current to the second heating film 1302. Upon receiving the current, the second heating film 1302 further heats the aerosol precursor and completes the atomization process. This arrangement method not only reduces the complexity of the circuit, but also can control the temperature distribution of the heating films on the two surfaces, so as to meet different power requirements.
[0057] Optionally, the conductor 140 may be selected form materials with high electrical conductivity, such as copper, silver, or a conductive ceramic, while having high mechanical strength and high temperature resistance. The fabrication of the conductor 140 can be achieved by filling metal paste into the through hole 1101 and performing high-temperature sintering, to form the conductive connection. In some alternative embodiments, a conductive layer may be deposited on a wall of the through hole 1101 by using a metal plating technology, and connected to the heating films or the electrodes through welding or bonding.
[0058] Further, the shape and size of the conductor 140 are selected according to the size of the through hole 1101 and the structural requirements of the atomization core 100, to ensure reliable conductive and heat transfer effects.
[0059] As shown in FIG. 2, in some embodiments, the pair of electrodes 120 are respectively arranged on the intake surface 101 and the atomization surface 102 of the substrate 110. Further, the pair of electrodes 120 may be arranged at two ends of the substrate 110, respectively. Specifically, the pair of electrodes 120 includes a first electrode 1201 and a second electrode 1202, the first electrode 1201 is arranged at an end of the substrate 110, and the second electrode 1202 is arranged at an end opposite to the first electrode 1201.
[0060] Further, the first electrode 1201 includes a first sub-electrode 1203 and a second sub-electrode 1204. The first sub-electrode 1203 is arranged on the intake surface 101 and used to provide electrical energy to the first heating film 1301 arranged on the intake surface 101. The second sub-electrode 1204 is arranged on the atomization surface 102 and used to provide electrical energy to the second heating film 1302 arranged on the atomization surface 102.
[0061] Further, the second electrode 1202 includes a third sub-electrode 1205 and a fourth sub-electrode 1206. The third sub-electrode 1205 is arranged on the intake surface 101 and used to provide electrical energy to the first heating film 1301 arranged on the intake surface 101. The fourth sub-electrode 1206 is arranged on the atomization surface 102 and used to provide electrical energy to the second heating film 1302 arranged on the atomization surface 102.
[0062] Such distributed electrodes can ensure that the heating films of the intake surface 101 and the atomization surface 102 can be independently heated and operate in coordination, so as to improve the atomization effect of the atomization core 100.
[0063] Further, the first heating film 1301 is coupled between the first sub-electrode 1203 and the third sub-electrode 1205, and covers a first partial region of the intake surface 101 and is used to heat and pretreat the aerosol precursor in this region.
[0064] Further, the first heating film 1301 includes a plurality of first vias 1303 aligned with the through holes 1101 in the first partial region of the intake surface 101, so as to ensure that the aerosol precursor can pass through the first heating film 1301 without affecting its heating effect.
[0065] Further, the second heating film 1302 is coupled between the second sub-electrode 1204 and the fourth sub-electrode 1206, and covers at least a second partial region of the atomization surface 102 and is used to further heat the aerosol precursor transmitted from the intake surface 101, thereby achieving sufficient atomization.
[0066] Further, the second heating film 1302 includes a plurality of second vias 1304 aligned with the through holes 1101 in the second partial region of the atomization surface 102, so as to ensure that the aerosol precursor transmitted from the first heating film 1301 can pass through the second heating film 1302.
[0067] In this way, the first heating film 1301 and the second heating film 1302 are both connected between the first electrode 1201 and the second electrode 1202. In this parallel circuit configuration, the heating power of the first heating film 1301 and the second heating film 1302 can be independently adjusted according to requirements, thereby achieving precise temperature control of the atomization core 100. Meanwhile, through the double-sided heating method of the intake surface 101 and the atomization surface 102, it can be ensured that the aerosol precursor is uniformly heated and fully evaporates, thereby improving the atomization efficiency.
[0068] In addition, the number, size, and arrangement method of the first vias 1303 and the second vias 1304 may be selected according to the actual requirements of the atomization apparatus, so as to improve the smoothness of the aerosol precursor transmission and heating uniformity to the greatest extent.
[0069] In some embodiments, a pair of conductors 140 include a first conductor 1401 and a second conductor 1402. The first conductor 1401 is connected to the first sub-electrode 1203 and the second sub-electrode 1204 through passing through a corresponding through hole 1101, thereby realizing electrical conduction between the intake surface 101 and the atomization surface 102. Such arrangement method ensures that the first electrode 1201 forms a continuous electrical connection path between the heating films on the two sides, to meet the requirements of double-sided heating.
[0070] Further, the second conductor 1402 is connected to the third sub-electrode 1205 and the fourth sub-electrode 1206 through passing through a corresponding through hole 1101, thereby realizing electrical conduction of the second electrode 1202 between the intake surface 101 and the atomization surface 102. Such arrangement method ensures that the second electrode 1202 can provide a reliable current circuit between the intake surface 101 and the atomization surface 102.
[0071] In other words, through the arrangement of the first conductor 1401 and the second conductor 1402, the first electrode 1201 and the second electrode 1202 form an efficient electrical circuit between the intake surface 101 and the atomization surface 102. Specifically, the first conductor 1401 and the second conductor 1402 respectively correspond to two groups of sub-electrodes of the first electrode 1201 and the second electrode 1202, ensuring that the electrical connection of the two pairs of sub-electrodes is seamlessly connected.
[0072] In this way, through the arrangement of the aforementioned distributed electrodes and the conductors 140, the dual sub-electrode structure of the first electrode 1201 and the second electrode 1202 ensures synchronous heating between the intake surface 101 and the atomization surface 102, and improves the operating efficiency of the atomization core 100.
[0073] As shown in FIG. 3, in some embodiments, the pair of electrodes 120 are arranged on the intake surface 101 or the atomization surface 102 of the substrate 110. Further, the pair of electrodes 120 may be arranged on the intake surface 101 or the atomization surface 102 of the substrate 110. Specifically, the pair of electrodes 120 includes a first electrode 1201 and a second electrode 1202, the first electrode 1201 is arranged at an end of the substrate 110, the second electrode 1202 is arranged at an end opposite to the first electrode 1201, and the first electrode 1201 and the second electrode 1202 are located on the same side. Further, the first electrode 1201 and the second electrode 1202 are both arranged on the atomization surface 102 and used to provide electrical energy to the second heating film 1302 arranged on the atomization surface 102. Further, the second heating film 1302 provides electrical energy to the first heating film 1301 arranged on the intake surface 101 via a conductor 140.
[0074] This not only enables distributed power supply of the circuit, but also ensures that the heating films on the intake surface 101 and the atomization surface 102 can operate independently or cooperatively, and the temperature and the heating power can be flexibly regulated according to requirements.
[0075] Further, the first heating film 1301 covers at least a first partial region of the intake surface 101, and is used to preheat the aerosol precursor, thereby improving the subsequent atomization effect.
[0076] Further, the first heating film 1301 includes a plurality of first vias 1303 aligned with the through holes 1101 in the first partial region, allowing the aerosol precursor to flow from the intake surface 101 to the atomization surface 102 without interfering with the fluidity and heating effect of the aerosol precursor.
[0077] Further, the second heating film 1302 includes a first heating part 1305 and a second heating part 1306 respectively covering different regions of the atomization surface 102. Specifically, the first heating part 1305 is coupled to the first electrode 1201 of the pair of electrodes 120. Further, the first heating part 1305 covers at least a second partial region of the atomization surface 102, and is used to heat the aerosol precursor in the second partial region to realize atomization. Further, the first heating part 1305 includes a plurality of second vias 1304 aligned with the through holes 1101 in the second partial region to ensure that the aerosol precursor can pass through effectively and be heated uniformly.
[0078] Further, the second heating part 1306 is coupled to the second electrode 1202 of the pair of electrodes 120. The second heating part 1306 covers at least a third partial region of the atomization surface 102, and further heats the aerosol precursor to achieve a fully atomization state.
[0079] Further, the second heating part 1306 includes a plurality of third vias 1307 aligned with the through holes 1101 in the third partial region. In this way, the first heating film 1301 on the intake surface 101 preheats the aerosol precursor, enabling it to reach a suitable temperature before entering the atomization surface 102. The second heating film 1302 on the atomization surface 102 is arranged in a partitioned manner (that is, the first heating part 1305 and the second heating part 1306) , and performs staged heating and atomization treatment on the matrix in different regions respectively, ensuring uniform and efficient atomization.
[0080] In this way, the first heating part 1305 and the second heating part 1306 of the second heating film 1302 are respectively coupled to different electrodes, so that the power and the temperature of each heating region can be independently controlled, thereby adapting to different atomization requirements.
[0081] In some embodiments, a first conductor 1401 of the pair of conductors 140 passes through a corresponding through hole 1101 and is connected between the first heating film 1301 and the first heating part 1305 of the second heating film 1302. Further, an end of the first conductor 1401 is coupled to the first heating film 1301 on the intake surface 101, and the other end is coupled to the first heating part 1305 of the second heating film 1302 on the atomization surface 102. The first conductor 1401 establishes a conductive path between the first heating film 1301 and the first heating part 1305.
[0082] Further, a second conductor 1402 of the pair of conducting bodies 140 passes through a corresponding through hole 1101 and is connected between the first heating film 1301 and the second heating part 1306 of the second heating film 1302. Further, an end of the second conductor 1402 is coupled to the first heating film 1301 on the intake surface 101, and the other end is coupled to the second heating part 1306 of the second heating film 1302 on the atomization surface 102. The second conductor 1402 establishes a conductive path between the first heating film 1301 and the second heating part 1306, so that the current can drive the second heating part 1306, and complete heating requirements of different regions of the atomization surface 102.
[0083] In this way, the first conductor 1401 and the second conductor 1402 are respectively connected to different heating regions, thereby realizing the current distribution and heating between the intake surface 101 and the atomization surface 102. This allows the heating power and the temperature of each heating region can be independently regulated, adapting to various atomization requirements. In addition, by changing the positions of the first conductor 1401 and the second conductor 1402, the heating power distribution of different regions can be achieved, thereby meeting various requirements of the atomization apparatus.
[0084] In some embodiments, the first conductor 1401 of the pair of conductors 140 passes through the through hole 1101 and is connected between the first heating film 1301 and the first heating part 1305, with the connection position located on a side away from the first electrode 1201. The second conductor 1402 of the pair of conductors 140 passes through the other through hole 1101 and is connected between the first heating film 1301 and the second heating part 1306, with the connection position located on a side away from the second electrode 1202. Through this arrangement method, effective electrical connection can be achieved between the first heating film 1301 and the first heating part 1305, and between the first heating film 1301 and the second heating part 1306, ensuring that the current can be conducted to each heating region, thereby driving the heating films to generate heat.
[0085] In some embodiments, if the first heating film 1301 and the second heating film 1302 are made of the same material, they will have similar thermal conductivity and resistance characteristics. This ensures consistency of heating efficiency, and is suitable for the atomization core 100 that requires uniform heating.
[0086] In some embodiments, if the first heating film 1301 and the second heating film 1302 are made of different materials, the resistance characteristics and thermal conductivity of the corresponding heating films can be adjusted according to different heating requirements. By selecting different materials, more precise temperature control and heating power distribution can be achieved. For example, a high thermal conductivity material is used in some regions to improve heating efficiency, while a low thermal conductivity material is used in other regions to realize local control of temperature.
[0087] In some embodiments, the first heating film 1301 or the second heating film 1302 may be made of a material having a fusing characteristic (for example, similar to a function of a fuse) , and can be automatically fused to break circuit when an operating current or temperature of the atomization apparatus exceeds a predetermined threshold.
[0088] When the current or the temperature in the atomization apparatus reaches a certain predetermined threshold, the material in the heating film undergoes a physical change, such as melting, breakage, or other similar phenomena, which causes the conductive path of the heating film to be opened, thereby cutting off the current supply.
[0089] Optionally, the fusing temperature can be precisely controlled by the selection of the material and the thickness of the heating film.
[0090] When the atomization apparatus operates normally, the first heating film 1301 or the second heating film 1302 efficiently heats the aerosol precursor within a current or temperature range, to provide a stable atomization effect. However, under an abnormal situation, for example, abnormal battery power supply (such as excessive power supply) , circuit failure, or exhaustion and dry burning of the aerosol precursor (e.g., E-liquid) , the temperature or current may exceed the predetermined threshold, thereby triggering the fusing characteristic, and the first heating film 1301 or the second heating film 1302 may be automatically fused, causing the circuit to be opened and stop generating heat. This can prevent the aerosol precursor from overheating to generate harmful substances or damage the device.
